CARPE T-CLE ANING MACHINE.

Specification of Letters Patent.

Patented June 8, 1909.

Application filed April 29, 1908. Serial No. 430,014.

carpet cleaners, in which a machine, or

carriage, on two rotary floor wheels, is

adapted to be pushed to, and fro, on a carpet, or floor, said machine having a forward and lower mouth in proximity to the floor, and provided with front and rear bellows, adapted to reciprocal movement, and co-acting together, to draw dust and air through said mouth and lodge the dust in-one receptacle,

or chamber, and 7 means in the adjoining chamber to receive air and assist the opera- .tion of the machine.

The objects of my invention are, first to remove all dust from carpets and floors, second, to provide means whereby the dust can be easily removed from the machine, third,

, to provide means whereby folds, creases,

fibers of carpet or any unevenness of carpet,

are prevented from entering the mouth of the machine. I attain these objects by the mechanism illustrated in the accompanying drawing in which Figu showln the front bellows extended and the rear be lows closed. Fig. 2 is a plan of the valves, in the forward and rear sides ofthe outer part of the dust box. I ig'. 3 is a sectional elevation of the machine througl1 the broken line B, B, of Fig. 2 of thejdrawing.

. Fig. 4 is a sectional elevation Ofthe machine through the broken line A, A, of Fig. 2 of the drawing. Fig. 5 is an enlarged side elevation of the adjustable bearings of the floor wheels, both sides of the machine being similar. Fig. 6 is a plan of Fig. 5, of the drawing. Fig. 7 is an enlarged side'elevatlon of the side strap, or connecting rod.

Similar characters refer to similar parts throughout the several views.

In the drawing, the machine or portable carriage, is indicated by C, and comprises abox having a dust receptacle E and an air chamber l), separated by a pilltltlti all F.

re 1 is a side elevation of the machine,

1 H, is the lower forward nose part of the machine C, and extends beyond the forward and extended bellows J, and transversely to the breadth of the machine. .The'opposite or rear part of the machine has a similar bellows K, shown closed, or contracted. The said forward extension H, is shown resting on a floor, or carpet M, and has a mouth, or-

transverse elongated slot, or opening X,

[which communicates with the dustreceptacle- E, through the lower part of said receptacle,

as indicated by arrow in Fig. 3 of the draw ing. In the forward nose part H, are three,

more or less divisional walls 2, of light ma terial. Thewalls 2, prevent any elongated material, such as fiber, or other matter, from entering the mouth N, of the machine.

P, are side floor wheels, of suitable material, and are journaled in the adjustable bearings R, which are adjustably secured to the sides of the machine by means of scre'ws 3, and 4. The bearings B, have slots 5, to allow the upper hub part6 of the bearing to be raised, to. bring the wheels P to close contact with the wheels S.v The weight of the machine is borne by the-floor wheels P, when operating. side wheels S are of suitable material and secured on the transverse shaft T, which is adapted to rotate, in either direction, in the stationary transverse tube, or sleeve U,

which extends through the machine, and shown in. Figs. 2,3 and 4 of the drawing.

The side wheels P, drive the side wheels S, by close contact, one with the other, or trio-- tion, the side bearings R, are adapted to bring the peripheries of the floor Wheels to contact with the peripheries of.-the upper wheels.

V, are crank pins on the wheels S, and

The upper and forward operate in the vertical slots ,8, in the side straps, or connecting rods W, the ends of which are suitably secured to the outer ends of, the bellow J, and K, to operate or recip-' rocate said bellows.

'9, is a common two arm liandle,.suitably 1 connected to the sides of the machine to alternately.

12 and 18, are opposite and similar valves on the inner sides of the forward and rear walls respectively, of the air chamber D, and cover the similar openings 14 and 15 in said walls 16 and 17 are opposite -and similar valves on theouter sides of the forward and 7 rear walls respectively, of the dustreceptacle E, and cover the similar openings 18 and 19 in said Walls. The valves referred to arevery light and sensitive and operate by the movement of the bellows, that is,-by

I air propulsion and suction, forv instance,

when the bellows J, is extending, the valve 12 closes, and the valve 16 opens, and when,

the bellows-J is closing, the valve 12 opens and the valve 16 closes. The opposite bellows K, together with the opposite valves 13 and 17 operate in like manner.

20-is a removablecover on the receptacle E, and'22 is a removable cover on't'he chamber D; The inwardly extended cover 22, on the chamber D, is of fabric material and extends a suitable distance in said chamber a shown in Fig. 4: of the drawing. The cover 22 affords air escapement through the same The inwardly extended fabric cover, referred to, has an inner strengthening rib :23 which extends to the inner lower part of the same, said "rib having an opening 24: for thehand to lift said inverted cover out of theichamber for cleaning and the like.

When the machine is in operation, the dust. enters through the opening N, thence into the receptacle E, and finds lodgment therein. Air passes through the opening 18 and also through the opening 1 1 and into the air chamber D. The receptacle E, may be easily emptied of dust by removing the cover 20. More or less air passes through all the openings of the valves when oper- 'ating.

What I claim as my invention and desire to secure by Letters Patent, is

1. In a carpet cleaning machine a divided box provided with an extension having a sectional mouth on its lower front part communicating with one division of the box,

bellows on the front and rear of the box, a

removable fabric cover inwardly extending in the box, ad ustable floor wheels on the sides of the box and means connecting said operate the same.
